Abstract

본 발명은 하기의 구조식(I)을 갖는 광변색제(光變色劑)인 스피로계 화합물 2 내지 6 중량%를 59 내지 73 중량%의 일액형, 저점도의 에폭수지에 균질하게 용해시키고, 스피로계 화합물이 용해된 에폭시수지에 25 내지 35 중량%의 부틸셀루솔브(Butylcellusolve)를 더욱 적가하면서 용해시켜 수득한 조성물에 자외선안정화제로서 소량의 시아솔브-1084(Cyasorb-1084), 타누빈(Tinuvin) 또는 티누빈-144, 벤조페논 화합물 또는 아민계 화합물을 더욱 첨가하므로써 잉크 조성물을 수득함을 특징으로 한다.The present invention homogeneously dissolves 2 to 6% by weight of a spiro-based compound, a photochromic agent having the following structural formula (I), in a one-component, low viscosity epoxy resin of 59 to 73% by weight, A small amount of siasorb-1084 (Cyasorb-1084), tanuvin (Tinuvin) as an ultraviolet stabilizer was added to the composition obtained by further dissolving 25-35% by weight of butylcellusolve in an epoxy resin in which the compound was dissolved. Or tinuvin-144, a benzophenone compound or an amine compound is further added to obtain an ink composition.

본 발명에서 사용되어지는 광변색제(I)는 통상 빛에너지의 흡수 및 방출에 의하여 발색 및 소색되어지는 물질로서, 바람직하게는 스피로계 화합물이다.The photochromic agent (I) used in the present invention is a material which is usually colored and discolored by absorption and emission of light energy, and is preferably a spiro-based compound.

상기식에서, R₁은 수소, 메톡시나 에톡시 등과같은 알콕시, 할로겐 원자 또는 트리플루오로메틸이고, R₂는 수소 또는 메틸이나 에틸 등과 같은 알킬이며, R₃는 수소, 디메틸아민 또는 디에틸아민 등과 같은 아민, 피페리딘 또는 물포린(molpholine)이고, R₄는 수소, 메톡시나 에톡시 등과같은 알콕시 또는 할로겐 또는 나프탈렌 등과같은 여러가지 방향족 고리 화합물이고, B는 벤젠 또는 나프탈렌 등과같은 여러가지 방향족 고리 화합물 또는 헤테로고리 화합물이다.Wherein R ₁ is hydrogen, alkoxy such as methoxy or ethoxy, halogen or trifluoromethyl, R ₂ is hydrogen or alkyl such as methyl or ethyl, and R ₃ is hydrogen, dimethylamine or diethylamine Amines such as amine, piperidine or molpholine, and R ₄ is hydrogen, various aromatic ring compounds such as alkoxy or halogen or naphthalene such as methoxy or ethoxy, and B is various aromatic rings such as benzene or naphthalene Compound or heterocyclic compound.
